A hobbyist made a 2x2 angled LEGO brick with a computer and an OLED display embedded into it: [this video] This is a mind blowing level of miniaturization, especially considering that this was assembled by someone at home with commercially available off-the-shelf parts! The fact that he used a cheap, readily available 3D printer to manufacture the jigs and mould parts is the icing on the cake. When I grew up, computer monitors were heavy and had big vacuum tubes in them made out of thick glass. At the scale of a LEGO brick, it was already amazing having a single LED light instead of an incandescent light bulb! A working computer!? With a display? Madness!
Hobbyist builds a computer with OLED display inside a LEGO brick.
as you mention gaming – do you know the doom-in-lego-brick? [link] and brick assembly [this video] There are some video links in the (german) article [link] . Mind-blowing.
His stuff is fascinating. He first came to my attention when he built the working LEGO computer bricks, as shown here: [this video] This shows it being built but if you want to see it working, jump to just after 12 minutes.
Build of the working LEGO computer bricks; working demo after 12 minutes.
An earlier iteration of the same block is imo more impressive in its creativity - [this video] - such an unexpected and yet completely natural extension of the brick set.
Earlier brick iteration, a creative natural extension of the brick set.
